在水平地震作用下高层建筑的变结构控制

The Variable Structure Control for Horizontal Seismic Responses of High Buildings

从改变结构刚度和阻尼能改变结构动力特性的概念出发，提出了变结构控制方法，并采用复模态分析理论对变结构控制状态及其减震效果进行了优化分析．

On the basis of the concept that changing the structural stiffness and damping can change the structural dynamic property,the variable structural control method is proposed.Then,by using the complex modality theory,the control state of the variable structure and the effect of seismic reduction are analyzed optimally.
